How to redirect to a page (without branching and without pl/sql)

Hi,
Have a requirement where when a user log into the application, the APP_USER must be checked against the list of users maintained in a database table, if APP_USER name exist in the table, the user must be redirected to the home page else user must be redirected to the Registration page.
Tried the branching concept:
Branch Point: On Load: Before Header
Condition: NOT Exists (SQL Query returns no rows)
Expression1 : select * from users_tab where name = v('APP_USER')
When this condition is given, though the user name does not exist in the users_tab, the page is redirected to page 1 instead of the Registration page.
Where is the problem here?
How can it be resolved?
Is there an alternative way to implement this?

select * from users_tab where upper(name) = nvl(:APP_USER,'X')

How to redirect to different page after login in APEX 4.1

Dear All,
Here my Requirement is,When the users login,
when they entered their username and password and pressed login button,
they have to redirected to different pages based on the type of user.
Here my LOGIN_TABLE has following 3 columns,
1.Username
2.Password
3.Type.
The TYPE has 2 values, employee and admin.
when the type is admin they should be redirected to page 2,
reaining i.e employee users has to be redirected to page 3.
How can I do this? please give some suggestion.
Thank you.

Dear Christian,
Thank you for your reply,
I would like to explain something,
When I using the following function,
*create or replace FUNCTION custom_auth_g (
p_username IN VARCHAR2,
p_password IN VARCHAR2)
RETURN BOOLEAN IS
BEGIN
FOR c1 IN (SELECT 1
FROM login_table
WHERE upper(username) = upper(p_username)
AND upper(password) = upper(p_password))
LOOP
RETURN TRUE;
END LOOP;
RETURN FALSE;
END;*
When login, It checks in the login_table table and if the username is exist with the pass word it successfully entered inside the application.
for all users only one page which we set.
My Login_table also contains type which has 2 type as I mentined above.
But As I mentioned earliar based on the user type it has to be redirected to 2 different page.
I found this Package but I cant understand,Can you please Explain?

How to redirect to other page in a dialogListener?

Hi All,
I am using JDeveloper 11g with ADF BC.
How to redirect to another page from a dialogListener of <af:dialog>?
I have a page with a [Delete] button on it. When user click on the delete button, a confirmation dialog will appear to ask "Are you sure? [Yes/No]". If user answer [Yes], I will delete the current record, and go to another page. I can call a Operation Binding in the dialogListener, but I don't know how to go to another page.
public void handleDeleteDialog(DialogEvent dialogEvent) {
OperationBinding operationBinding = bindings.getOperationBinding("Delete");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
// redirect to another page?

You can also make usae of Navigation Handler to invoke the navigation action in your task flow as
FacesContext facesCtx = FacesContext.getCurrentInstance();
NavigationHandler nh = facesCtx.getApplication().getNavigationHandler();
nh.handleNavigation(facesCtx, "", "ActionNameInTaskFlow");

How to redirect a JSP page after the session is killed

Hello!
I am quite new to JSP. I have a question about how to redirect a jsp page after the session is killed. Could anyone help?
thanks a lot in advance!

You can't, directly. There's no connection betweenthe server and browser.
even after invalidating the session. we can do it
directly using the statement
response.sendRedirect("....");
or we can use the meta refresh tag.if session is invalidated and if we try to do response.sendRedirect(".. ") it throws IllegalStateException

How can I rearrange the pages in a PDF without changing the assigned paged numbers.

How can I rearrange the pages in a PDF without changing the assigned paged numbers? These correspond to the original document folio numbers.

In theory it would be possible to 'record and play back' the page numbers using a folder-level script, but it's far from trivial. You would have to use the doc.movePage() function - presumably driven by a dialog box - to do the page shuffling so there was a way to track what was being done, then swap the page 'labels' of the two affected pages. That's where it gets messy.
We have functions in the JSAPI which can read and write the page label, but they don't do things in a logical way. The 'getPageLabel()' function simply returns a string, but the 'setPageLabel()' method expects to be told the numbering scheme, prefix, etc. You'd have to parse the string and work out what scheme it was implementing.

How do I set up pages for mac and ipad to share a document and keep them synced.

How do I set up pages for mac and ipad to share a document and keep them synced.

You can upload them from Mac to iCloud and then download on the iPad. They only directly sync between iOS devices. The Mac version of Pages has more options that are not available on iOS. If you use a font that is not available on iOS it will change the font. Some layout options aren't available either.

What is the procedure for a hard boot of my iPod touch 4th generation without itunes, and without computer, and without iPod data screen.?

What is the procedure for a hard boot of my iPod touch 4th generation
without iTunes, and without computer, and without iPod data screen?
6 months after purchase I updated my iPod touch as recommend by iTunes.
It has not worked since that day. It frozen (disabled) with a "connect to
iTunes" icon displayed...that is the only thing it does. itunes does not
recognize the iPod. My Windows7 computer recognizes an Apple device.
Other computers recognize the devise but if iTunes resided on that
computer it did not recognize the iPod
I suffered a setback with deep depression and am just now getting out of it enough to do something. The depression prohibited me from taking action.
I have done every procedure recommended from Apple help and external
sources. I did this thoroughly with help for other owners and IT experts,
Apple employees etc etc. I and associates have perform reboots utilizing a
number procedure using only button on the iPod. These were unsuccessful
also have performed.
Please do not ask me to do the usual.
Online I saw a process using the buttons on the iPod to completely
reformat
the iPod. It was NOT the hold buttons for 10 sec let go of one wait 8 sec
etc. I can not find the process now...a friend showed it to me in passing
I have lost contact with him. This is the procedure, I believe, that with
enable me to update and use the iPod.

You need an internet connection and likely a computer with iTunes but an iPhone, iPad or iPod touch with the FindMy iPhone App may work by:
If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone and use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
You can also wipe the iOS device by installing the FindMyiPhone app on another iOS device and using that app to wipe the device.
Otherwise
Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.
Yo may have to go to an Apple store or a friend's house with an internet connection and iTunes.

Data fetch from table without Refresh and without using tab key.

hi Friends,
I have a problem i want to extract data from table without Refresh into text field without using Tab key. when i'll enter any value in a text field then corressponding value should come in to corressponding textfield without using Tab Key.
eg. when i enter emp_id 101 in a text field then the first_name and last_name ,adress should come in to corressponding text fields without refresh and without using Tab key.
How Can I do this.
Thanks
Manoj

Hi Manoj,
I assume that this is similar to: Data fetch without Refresh rather than Re: Value of one textfield should come into another textfield Without Using TAB ?
If so, the only change you need to make on the first one is to use "onkeyup" instead of "onchange" in the item's "HTML Form Element Attributes" setting.
Note, however, that the user must move away from the item at some point (for example, to click a button), so the onchange will be triggered anyway.

Iphone without contract and without sim LOCK

hi, can I buy the iphone without contract and without sim LOCK?? if then where, for information binn I sechr gratefully. greeting

Actually, you don't HAVE to sign a two year contract with AT&T, you can use the GO Phone option and do a month-to-month payment.
The drawback to that is that for your $50/month you get less than half as many minutes and no pre-paid SMS. You do, however, get unlimited internet turning your iPhone into a miniature laptop that you pay way too much to use each month... grin
I'm on the GO Phone option until my stupid T-Mobile contract expires later this year...

How to redirect to a page after login fails?

Since I am working on an automated login from Forms I would like the login page to redirect to an error page if the login fails. I can't seem to find an option for this.
I am using a public page that branches to 101 with BRANCH_TO_PAGE_ACCEPT, but when login fails I see this login page.
Instead of that I would like to redirect to a public page that shows a message.
How can I do this?
Wendy

A login failure is when the user and/or pass is not correct. I do not want to show page 101 but a different page when this happens.
I am using the default login page but I am calling it with BRANCH_TO_PAGE_ACCEPT so the user never sees it and I want to keep it that way....

How to redirect to a page dynamically after authentication Apex

We have developed an application and the application id is 333.
we have developed a login screen(page No. 111).
After login Company page (Page No.1) will appear where the user selects the company name.
Once company is selected, the control goes to Menu Page(Page No.10). The menu will be displayed based on the user rights.
In shared Components - Authentication scheme,
     In session Not Valid region, URL option is selected and URL is assigned as "we have given "f?p=&APP_ID.:111:&SESSION."
     In Logout URL, URL option is enabled and URL is assigned as "f?p=&APP_ID.:111"
In shared Components - Security Attributes,
     In Authentication region, in HOME link "f?p=&APP_ID.:1:&SESSION." is assigned
In login page (Page No. 111), we have created a process "On Submit - After computation and validations".
     in that
          we are checking a condition like
          if the user has access to Only one company then he will be redirected to Menu_page(Page No.10).
          if the user has access to more than one company then he will be redirected to Company Page(Page No.1).
if "No. of company access" =1 then
wwv_flow_custom_auth_std.login (p_uname => :p111_username,
p_password => :p111_password,
p_session_id => v ('APP_SESSION'),
p_flow_page => :app_id||':10'
else
wwv_flow_custom_auth_std.login (p_uname => :p111_username,
p_password => :p111_password,
p_session_id => v ('APP_SESSION'),
p_flow_page => :app_id||':1'
end if;
The above condition is not working. ie. it is always loading Company Page(Page No.1) even if the user has access to one company alone.
Can anyone point out the place where I have done wrong. Or please suggest me a method to achieve the above said task.

Hi User490632,
During the login,
it using the custom authentication function which I mentioned below,
*create or replace FUNCTION custom_auth_g (
p_username IN VARCHAR2,
p_password IN VARCHAR2)
RETURN BOOLEAN IS
BEGIN
FOR c1 IN (SELECT 1
FROM login_table
WHERE upper(username) = upper(p_username)
AND upper(password) = upper(p_password))
LOOP
RETURN TRUE;
END LOOP;
RETURN FALSE;
END;*
its working fine, If I give the username and password which exist in the table login_table.
Now I need to redirect to 2 different pages.
if the username is 'guru' then when he clicked the login button he has to redirect to page 2,
if username is any other name except 'guru' they have to be redirected to page 3.
Can you please give the step by step procedure to follow?
Thank you.

gurujothi
